Question

The coordinates of a point P on a two-dimensional plane can be represented by P(x, y) with x as the x-coordinate and y as the y-coordinate. The coordinates of the midpoint of two points P1(x₁, y₁) and P₂(x₂, y₂) can be calculated as P(x, y) where:

Design a class Point with the following details: Class name: Point 

Data Members/instance variables: 

x: stores the x-coordinate 

y: stores the y-coordinate 

Member functions:

Point (): constructor to initialize x = 0, y = 0 

void readpoint (): accepts the coordinates x and y of a point Point midpoint (Point A, Point B): 

calculates and returns the midpoint of the two points A and B 

void displaypoint (): displays the coordinates of a point 

Specify the class Point giving details of the constructor (), member functions void readpoint ( ), Point midpoint (Point, Point) and void displaypoint () along with the main () function to create an object and call the functions accordingly to calculate the midpoint between any two given points.

Answer 1

import java.io.*; 

class Point 

{ 

int x; 

inty; 

public Point () 

{ 

x = 0; 

y = 0; 

} 

public void read point () throws IOException 

{ 

Buffered Reader br = new BufferedReader(new 

InputStreamReader(Systemin); 

System.out.println("Enter the value of x''); 

x = Integer.parselnt (br. readLine()); 

System.out.printing'Enter the value of y "); 

y = Integer.parselnt(br. readLine ( )); 

} 

public Point midpoint(Point A, Point B) 

{ 

x = (A.x+B.x)/2; 

y = (A.y + B.y)/2;

} 

public void displaypoint() 

{ 

System.out.println(x); 

System. out.println(y); 

} 

public void main() 

{ 

Point obj 1 = new Point(); 

obj1.readpoint(); 

Point obj 2 = new Point(); o

bj2.readpoint(); 

Point obj 3 = new Point(); 

Point obj4 = obj3.midpoint(obj 1, obj2); 

obj4.displayPoint(); 

}
